Song meaning of Welcome to the Black Parade by My Chemical Romance

Welcome to the Black Parade is a song about a father who takes his son to see a marching band, but instead of enjoying the music like a normal kid, the father starts blabbering about defeating demons and saving broken people. The son probably thought, "Dad, chill, it's just a band." But little did he know that his father was a genius and had predicted his own death, and the only way to remember him was by creating a black parade. The song then talks about rising from the ashes and carrying on, even though the world is full of misery and hate. The singer declares that he won't apologize for being himself, and encourages everyone to embrace their scars and be who they are. In short, Welcome to the Black Parade is about a father who was a bit cuckoo, but had a vision that his son fulfilled with a rocking parade.
